hi everyone newbie here,i have a kodak aio printer(about 6 years old now) stopped printing today with a message saying"printhead loose or missing" with another message saying how to rectify the problem, which i have done now,about a dozen times, and still the same message pops up "printhead loose or missing"the ink cartridges are new, so does anyone think that a new printhead might solve the problem, many thanks in advance, Gwyn
